Seat Assembly
[0026]As shown in
[0027]The padding layer 112 may be manufactured from a number of materials (e.g., foam, feathers, cotton, memory foam, etc.). The material used for the padding layer 112 aids in providing support and comfort for the passengers of the vehicle 10 while the vehicle 10 is in operation or stationery. For example, memory foam reduces vibrations and shocks/impacts felt by the passengers during operation of the vehicle 10.
[0028]In some embodiments, the second base layer 118 is coupled to the seat frame 36. By way of example, the second base layer 118 may be detachably and/or pivotably coupled to the seat frame 36. According to an exemplary embodiment, the first base layer 114 and the second base layer 118 are configured to provide support for the seat bottom cushion 38. In particular, the first base layer 114 and the second base layer 118 aid in providing structural support to the dampening system 116 and/or the padding layer 112. In some embodiments, the first base layer 114 and the second base layer 118 are configured to be a mounting point for the dampening system 116 such that a portion of the dampening system 116 is attached to the first base layer 114 and the second base layer 118. The first base layer 114 and the second base layer 118 may also ensure that the dampening system 116 is properly aligned such that vibrations and shocks/impacts during operation of the vehicle 10 are properly distributed and dampened by the dampening system 116.
[0029]In some embodiments, the first base layer 114 and the second base layer 118 are manufactured from the same material. In some embodiments, the material used is plywood. Other materials such as steel or aluminum may also be used to manufacture the first base layer 114 and the second base layer 118. In other embodiments, the first base layer 114 is manufactured from a first material and the second base layer 118 is manufactured from a second material different from the first material.
[0030]According to an exemplary embodiment, the dampening system 116 is configured to improve the overall comfort and support of the passengers of the vehicle 10. The dampening system 116 may have mechanisms and systems configured to reduce an impact of vibrations and shocks/impacts transmitted from the vehicle 10 and/or an environment in which the vehicle 10 is in. The reduction in vibrations shocks/impacts reduces sudden movements that may be felt by the passengers, resulting in an improvement in comfort. Additionally, the dampening system 116 may be configured to improve longevity of the seat bottom cushion 38. Particularly, the dampening system 116 is configured to absorb energy/forces, which may have otherwise led to the destruction of the seat bottom cushion 38 (e.g., by damaging the material of the padding layer 112). As described in greater detail herein, the dampening system 116 may be or include at least one of a plurality of springs, a space frame, or a pneumatic system.
Dampening System
[0031]As shown in
[0032]The springs 120 may be manufactured from a number of materials (e.g., steel, titanium, copper, rubber) depending on cost restrictions, overall purpose and uses, etc. The springs 120 may be arranged in a number of ways depending on specific needs. For example, as is shown in
[0033]As shown in
[0034]The space frame 122 may be manufactured from a number of materials. In some embodiments, the space frame 122 is manufactured from an elastomeric material (e.g., rubber, silicone, polyurethane, etc.). The use of the elastomeric material for the space frame 122 allows for the space frame 122 to deform and reduce vibrations and shocks/impacts without compromising the structure. The space frame 122 may also be manufactured from other suitable materials that provide flexibility and shock/impact absorption capabilities.
[0035]As shown in
[0036]The pneumatic system 124 may also include a number of other components in order to improve functionality and performance of dampening. For example, the pneumatic system 124 may include a reservoir for storing compressed air, such that a consistent supply of air is available for the airbag 126. Additionally, the pneumatic system 124 may include a compressor for generating compressed air or additional valves or orifices for control amount of air entering and leaving the pneumatic system 124.
[0037]As utilized herein with respect to numerical ranges, the terms “approximately,” “about,” “substantially,” and similar terms generally mean +/−10% of the disclosed values, unless specified otherwise. As utilized herein with respect to structural features (e.g., to describe shape, size, orientation, direction, relative position, etc.), the terms “approximately,” “about,” “substantially,” and similar terms are meant to cover minor variations in structure that may result from, for example, the manufacturing or assembly process and are intended to have a broad meaning in harmony with the common and accepted usage by those of ordinary skill in the art to which the subject matter of this disclosure pertains. Accordingly, these terms should be interpreted as indicating that insubstantial or inconsequential modifications or alterations of the subject matter described and claimed are considered to be within the scope of the disclosure as recited in the appended claims.
